(Cisco network access control (NAC) is a plan initiated by Cisco and participated by many manufacturers. Its purpose is to prevent emerging hacker technologies such as viruses and worms from endangering enterprise security. With NAC, customers can only allow legitimate and trusted endpoint devices (such as PC, server, PDA) to access the network, and do not allow other devices to connect. In the initial stage, NAC can help Cisco routers implement access rights when endpoint devices enter the network. This decision can be made according to the information of the endpoint device, such as the current anti-virus status of the device and the operating system patch.
